Use the 2-space configuration by default and disable any formatting for
the demo/ subdirectory. The following command was used to generate this
change:
$ find . \( -name \*.cpp -o -name \*.h \) -exec clang-format \
--style=file -i {} \;

This topic removes ashmem from ART. Changes the names in system/extras
too. It only affects "dalvik-" ashmem regions which are the majority.
Test: run simpleperf_unit_test.
Test: run perfprofd_test.

ART may extract dex files into memory from zip files.
This CL supports getting symbols from extracted dex files in below steps:
1. Change map names in "/dev/ashmem/dalvik-xxx extracted in memory
from yyy.apk" format into yyy.apk!/xxx format.
2. Support dumping dex files in yyy.apk!/xxx format in JITDebugReader.
3. Support reading symbols from dex files in yyy.apk!/xxx format
in DexFileDso.
Also refactor FileHelper to return android::base::unique_fd,
refactor ArchiveHelper to wrap all operations to zip files.

Test: run simpleperf_unit_test.
Test: run simpleperf on an app containing extracted dex files.

1. Remove GetBuildIdFromApkFile and ParseSymbolsFromApkFile, because
their function can be supported using ApkInspector::FindElfInApkByName
and read_elf.h.
2. Remove ApkInspector::FindOffsetInApkByName, instead the caller can
use ApkInspector::FindElfInApkByName directly.
3. In ApkInspector::embedded_elf_cache_, add map for entry_name. So
the EmbeddedElfs added by cmd_record.cpp can be used by OfflineUnwinder.
Also support reading min executable virtual address from embedded elfs
in ElfDso.
Also avoid segfault reading build id of elf files with broken section
table, and add test.

Some APKs contain shared libraries that the linker handles
by mmap'ing directly from their APKs (if the library is
uncompressed and the proper manifest flag is set). With
this patch simpleperf now breaks out samples on a per-li
basis and reports the name of the lib within the APK.
Example output:
Cmdline: /system/xbin/simpleperf record -a sleep 30
Samples: 140672 of event 'cpu-cycles'
